Neon green spot on Whites Tree Frogs head.

For the record, I don't think it is a problem per-se if he insists on sleeping under the moss, it just means he is adapting to his environment in the way he sees fit. The trying to escape however is troubling. Here is my two cents, and if I'm breaking rules here I apologize, but stop misting. I don't mist my guys, they come from Australia, which is pretty dry, and to combat this they secrete a waxy film, that holds in moisture. The tarantula keeping community as a whole is starting to look down on misting, because spiders hate getting sprayed, and it causes humidity spikes, as you have seen. However they have found that humidity can be easily pumped up for tropical species by limiting air circulation, and increasing the surface area of wet items (like moss) in the tank. My guess is froggie is getting directly or indirectly misted, which is washing off his wax, and so he feels dry and tries to leave once the humidty drops from misting. Sure he could soak in the water bowl to keep wet, but what self respecting tree frog wants to live in the water bowl every night, when he could be exploring and find that place that is just right? My advice is to cover half of your screen top with saran wrap, and just keep the substrate moist and see how the humidity does. You can mist once in a while to make it feel like nature, but remember it doesn't rain every night in Australia. Keep in mind, my two cents is theory here, he may be bothered by noise or smells or any number of things, this is just the only conclusion I can make with the clues provided, and since it goes against convention, try at your own risk...

Half of my lid is covered in wrap and I only mist the moss though. I mist the substrate/moss in the morning and when I get home, it drops to about 45% humidity. I know where he sleeps in the moss so I never mist there because I don't wan't to disturb him.

I guess the only explanation is that he's upset about the rapid increase in humidity, it spikes to about 80% and then decreases to 45% by the morning. I'm finding it impossible to keep it at 50%-60% consistently. It spikes then gradually decreases in a cycle.
